What is the porosity of PTFE protective clothing fabric?

The new nanofiber masks on the market today are similar in appearance to ordinary masks, but the filter layer of the mask uses PTFE protective clothing fabric is a high-tech material. Let’s take a closer look below.

Protective clothing must have liquid barrier functions (water penetration resistance, moisture permeability, synthetic blood penetration resistance, surface moisture resistance), flame retardant properties and antistatic properties, There are requirements for breaking strength, elongation at break, filtration efficiency, and no skin irritation; it is also easy to put on and take off, the joints are tight, and the cuffs and ankle cuffs should be elastic.

The porosity of PTFE protective clothing fabric can reach 80%~90%, and has been processed by high-temperature heat setting. The microporous structure is stable and can effectively intercept dust particles. Moreover, its pore size is small and uniform, and it has a surface filtration mechanism. , easy to remove dust, with strong hydrophobicity and low surface energy, which can ensure the complete retention of impurities such as bacteria, while having a large flux. The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.

It is a PTFE protective clothing fabric manufacturer integrating production, sales and customization. The company has advanced PTFE membrane production lines and composite production lines. The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
